Consider This: Designing Via-in-Pad for Higher Density Flexible Circuits

May 31, 2021 | John Talbot, Tramonto Circuits

For flex circuit designs with high layer counts utilizing high density outer layers, the extra area utilized for separate pads and SMT components, severely limits the available space for trace fan out. By designing via-in-pad in flex and rigid flex circuits, it can significantly increase density, utilizing vias as mounting pads. The copper or silver filled flat vias allow for soldering components directly on via holes.

The Digital Layout: Test for Design—How Do You Measure Up?

May 25, 2021 | Kelly Dack, Printed Circuit Engineering Association

In this month’s column, Kelly Dack conveys the value of honing a skill set and the importance of being able to measure that skill set. Next, I hand it off to our PCEA Chairman Steph Chavez, who offers a positive outlook on PCEA activities over the summer months. Again, I am happy to provide our readers with a growing list of events which are coming up in 2021.

As the electronics industry undergoes dramatic change, it is essential for IPC to obtain advice and counsel from experts throughout the industry that help us navigate these changes. To this end, IPC created the Thought Leaders Program (TLP), a select group of experts who will generate ideas and insights.

Flexible Thinking: Process Flow for Occam QFN Test Vehicle

May 19, 2021 | Joe Fjelstad, Verdant Electronics

Joe Fjelstad teaches the Occam process through a series of steps and images. These solutions can significantly reduce the number of process steps required to manufacture an electronic module or assembly (perhaps by as much as one-third) and in the process making electronic assemblies more reliable and less costly by fundamentally focusing on the elimination of solder and the soldering process.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

May 14, 2021 | Nolan Johnson, I-Connect007

There is, increasingly, a sense of returning to “normal” daily life where I live. Of the state’s population, 35% have been immunized against coronavirus as of this week. Lockdowns are lifted, schools have partially reopened, and even some offices are staffing back up.
